Process of manufacturing a waterproof enclosure

ABSTRACT

A process of manufacturing a waterproof enclosure and sealing the waterproof enclosure includes the steps of forming a rectangular waterproof upper member and a rectangular waterproof lower member; forming four rectangular adhesive members; securing the adhesive members to the lower member by pressing and heating; securing three edges of the upper member to the lower member by pressing and heating to form a partially open enclosure having an open edge; punching a plurality of positioning holes on a periphery of the partially open enclosure; placing an article in the partially open enclosure by inserting the article through the open edge of the partially open enclosure; sealing the open edge of the partially open enclosure by pressing and heating to form a sealed enclosure; and cutting the periphery having the positioning holes to finish a waterproof enclosure.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to waterproof enclosure and more particularly to aprocess of manufacturing a waterproof enclosure and sealing anelectronic device with the waterproof enclosure.

2. Description of Related Art

A conventional waterproof device for protecting an electronic devicecomprises a wearable article having a waterproof enclosure; a rigidframe attached to the enclosure, the rigid frame defining an openinglarger than a cross-section of the electronic device; and a rigid covercoupled to the rigid frame, the cover being movable between an openposition in which the cover is disposed away from the opening, and aclosed position in which the cover forms a waterproof seal with theframe.

While the device enjoys its success in the market, continuingimprovements in the exploitation of waterproof device for electronicdevice are constantly sought.

SUMMARY OF THE INVENTION

It is therefore one object of the invention to provide a process ofmanufacturing a waterproof enclosure and sealing the waterproofenclosure comprising the steps of forming a rectangular waterproof uppermember and a rectangular waterproof lower member; forming fourrectangular adhesive members; securing the adhesive members to the lowermember by pressing and heating; securing three edges of the upper memberto the lower member by pressing and heating to form a partially openenclosure having an open edge; punching a plurality of positioning holeson a periphery of the partially open enclosure; placing an article inthe partially open enclosure by inserting the article through the openedge of the partially open enclosure; sealing the open edge of thepartially open enclosure by pressing and heating to form a sealedenclosure; and cutting the periphery having the positioning holes tofinish a waterproof enclosure.

The above and other objects, features and advantages of the inventionwill become apparent from the following detailed description taken withthe accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1 to 6, a process of manufacturing a waterproofenclosure and sealing an electronic device with the waterproof enclosurein accordance with the invention is illustrated. The process comprisesthe following steps:

Forming a rectangular waterproof upper member 2 made of flexiblematerial (e.g., plastic) and a rectangular waterproof lower member 3made of flexible material (e.g., plastic) is shown in FIG. 2.

Forming four rectangular adhesive members 4 made of PU (polyurethane) isshown in FIG. 2.

Securing the adhesive members 4 to the lower member 3 by pressing andheating and securing three edges of the upper member 2 to the lowermember 3 by pressing and heating to form a partially open enclosure 1having an opening 11 at one edge is shown in FIGS. 3 and 4.

Punching a plurality of positioning holes 5 on four edges of thepartially open enclosure 1 is shown in FIG. 4.

Placing an electronic device 6 in the partially open enclosure 1 byinserting the electronic device 6 through the opening 11 is shown inFIG. 5.

Sealing the open edge 11 of the partially open enclosure 1 by pressingand heating to form a sealed enclosure 1 is described.

Finally, cutting the four edges containing the positioning holes 5 tofinish a waterproof enclosure 7 is shown in FIG. 6.

While the invention has been described in terms of preferredembodiments, those skilled in the art will recognize that the inventioncan be practiced with modifications within the spirit and scope of theappended claims.

What is claimed is:
 1. A process of manufacturing a waterproof enclosureand sealing the waterproof enclosure comprising the steps of: forming arectangular waterproof upper member and a rectangular waterproof lowermember; forming four rectangular adhesive members; securing the adhesivemembers to the lower member by pressing and heating; securing threeedges of the upper member to the lower member by pressing and heating toform a partially open enclosure having an open edge; punching aplurality of positioning holes on a periphery of the partially openenclosure; placing an article in the partially open enclosure byinserting the article through the open edge of the partially openenclosure; sealing the open edge of the partially open enclosure bypressing and heating to form a sealed enclosure; and cutting theperiphery having the positioning holes to finish a waterproof enclosure.
